The system + provides a broad community of users with easy and timely access to + available spatial data and thematic maps from multidisciplinary sources, + that may in the end support informed decision making. The main goal of + the GNos software is to increase collaboration within and between + organizations for reducing duplication and enhancing information + consistency and quality and to improve the accessibility of a wide + variety of geographic information along with the associated information, + organized and documented in a standard and consistent way.</p><div class="highlights"><p>GeoNetwork Main Features</p><p><div class="itemizedlist"><ul type="disc"><li><p>Instant search on local and distributed geospatial + catalogues</p></li><li><p>Uploading and downloading of data, documents, PDF's and + any other content</p></li><li><p>An interactive Web map viewer that combines Web Map + Services from distributed servers around the world</p></li><li><p>Online map layout generation and export in PDF + format</p></li><li><p>Online editing of metadata with a powerful template + system</p></li><li><p>Scheduled harvesting and syncronization of metadata + between distributed catalogues</p></li><li><p>Groups and users management</p></li><li><p>Fine grained access control</p></li></ul></div></p></div></div><div class="section" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="N1002D"></a>GeoNetwork opensource background and its evolution</h2></div></div></div><p>The prototype of the GeoNetwork catalog was developed by the Food + and Agriculture Organization of the United Nations (FAO) in 2001 to + systematically archive and publish the geographic datasets produced + within the Organization. The prototype was built on experiences within + and outside the organization. It used metadata content available from + legacy systems that was transformed into what was then only a draft + metadata standard, the ISO 19115. Later on, another UN agency, the World + Food Programme (WFP) joined the project and with its contribution the + first version of the software was released in 2003 and operational + catalogues were established in FAO and WFP. The system was based on the + ISO19115:DIS metadata standard and embedded the Web Map Client InterMap + that supported Open Geospatial Consortium (OGC) compliant Web Map + Services. Distributed searches were possible using the standard Z39.50 + catalog protocol. At that moment it was decided to develop the program + as a Free and Open Source Software to allow the whole geospatial users + community to benefit from the development results and to contribute to + the further advancement of the software.</p><p>Jointly with the UN Environmental Programme (UNEP), FAO developed + a second version in 2004. The new release allowed users to work with + multiple metadata standards (ISO 19115, FGDC and Dublin Core) in a + transparent manner. It also allowed metadata to be shared between + catalogues through a caching mechanism, improving reliability when + searching in multiple catalogues.</p><p>In 2006, the GeoNetwork team dedicated efforts to develop a DVD + containing the GNos version 2.0.3 and the best free and open source + software in the field of Geoinformatics. The DVD was produced and + distributed in hard copy to over three thousand people and is now also + available for download from the http://geonetwork-opensource.org Web + site.</p><p>The latest release of GNos version 2.1, issued in late 2007, is + the result of another round of critical improvements, supported by FAO, + the UN Office for the Coordination of Humanitarian Affairs (UNOCHA), the + Consultative Group on International Agricultural Research (CSI-CGIAR), + UNEP and other donors. Support for the final metadata standard + ISO19115:2003 has been enabled by using the ISO19139:2007 implementation + specification schema published in May 2007. The release also serves as + the open source reference implementation of the OGC Catalog Service for + the Web (CSW 2.0.1) specification. Improvements to give users a more + responsive and interactive experience have been substantial and include + a new Web map viewer and a complete revision of search interface.</p></div><div class="section" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="N10038"></a>The use of Standards</h2></div></div></div><p>GNos has been developed following the principles of a Free and + Open Source Software (FOSS) and based on International and Open + Standards for services and protocols, like the ISO-TC211 and the Open + Geospatial Consortium (OGC) specifications. The GeoNetwork architecture + is largely compatible with the OGC Portal Reference Architecture, i.e. + the OGC guide for implementing standardized geospatial portals. Indeed, + the GNos’ own structure relies on the same three main modules identified + by the OGC Portal Reference Architecture, that are focused on spatial + data, metadata and interactive map visualization. GNos is also fully + compliant with the OGC specifications for querying and retrieving + information from Web catalogues (CSW 2.0.1). GNos supports the most + common standards to specifically describe geographic data (ISO19139 and + FGDC) and the international standard for general documents (Dublin + Core). It uses standards (OGS WMS) also for visualizing maps through the + Internet.</p></div><div class="section" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="N1003D"></a>Harvesting geospatial data in a shared environment</h2></div></div></div><p>Within the geographic information environment, the increased + collaboration between data providers and their efforts to reduce + duplication have stimulated the development of tools and systems to + significantly improve the information sharing and guarantee an easier + and quicker access of data from a variety of sources without undermining + the ownership of the information. The harvesting funcionality in GNos is + a mechanism of data collection in perfect accordance with both rights to + data access and data ownership protection. Through the harvesting + functionality it is possible to collect public information from the + different GeoNetwork nodes installed around the world and to copy and + store periodically this information locally. In this way a user from a + single entry point can get information also from distributed catalogues. + The logo posted on top each harvested record informs the user about the + data source.</p></div><div class="section" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="N10042"></a>GeoNetwork and the Open Source Community Development</h2></div></div></div><p>The community of users and developers of the GNos software has + increased dramatically since the release of version 2.0 in December 2005 + and the subsequent pre-releases of version 2.1. At present, the user and + developer mailing lists count nearly 200 subscriptions each. + Subscription to these lists is open to anyone interested. The archive of + the mailing lists provides an important resource for users and can be + freely browsed online. Members provide feedback within the community and + provide translations, new functionalities, bug reports, fixes and + instructions to the project as a whole. Building a self sustaining + community of users and developers is one of the biggest challenges for + the project. This community-building process relies on active + participation and interaction of its members. It also relies on building + trust and operating in a transparent manner, thereby agreeing on the + overall objectives, prioritization and long term direction of the + project. A number of actions have been taken by the project team to + facilitate this process.</p><p>The foundation for the establishment of a GeoNetwork Advisory + Board was laid at the 2006 workshop in Rome and membership criteria were + defined.</p><p>A work plan is presented and discussed at the yearly GNos + workshop; subsequently, the plan is maintained and updated throughout + the year where needed. The project management team reports back to the + advisory board about the reached developments and objectives during the + annual workshops.</p><p>Two public Websites have been established. One focuses on the + users of the software (http://geonetwork-opensource.org), while the + other one is dedicated to the developers + (http://trac-osgeo.org/geonetwork). Both can be updated and maintained + online by trusted members of the community. They provide documentation, + bug reporting and tracking, Wiki pages et cetera. A small part of the + community connects through Internet Relay Chat (IRC) on a public + geonetwork channel. But most interaction takes place on the user and the + developer mailing lists.</p><p>During the 2006 workshop, the project advisory board decided to + propose the GeoNetwork opensource project as an incubator project to the + newly founded Open Source Geospatial Foundation (OSGEO). This incubation + process is currently ongoing but close to conclusions. The project + Websites has been moved to servers accessible under the umbrella of the + OSGEO foundation. Web pages have been updated to reflect the OSGEO + principles and a source code review performed.</p><p>Source code is maintained in a publicly accessible code + repository, hosted at an independent service provider, SourceForge.net + that hosts thousands of FOSS projects. Developers and users have full + access to all sections of the source code, while trusted developers can + make changes in the repository itself. A special mailing list has been + established to monitor changes in the code repository. This so-called + "commit mailing list" delivers change reports by email to its + subscribers.</p><p>Standardizing documentation development is the next challenge + taken up by the project to ensure versioning and support of multiple + output formats (e.g. HTML and PDF).</p></div></div><div class="chapter" lang="en"><div class="titlepage"><div><div><h2 class="title"><a name="N10053"></a>Chapter 2.

In addition, GNos supports also the + international standard <span class="bold"><strong>Dublin Core</strong></span> for + the description of general documents.</p><p>This ISO Standard precisely defines how geographic information and + related services should be described, providing mandatory and + conditional metadata sections, metadata entities and metadata elements. + This standard applies to data series, independent datasets, individual + geographic features and feature properties. Despite ISO 19115:2003 was + designed for digital data, its principles can be extended to many other + forms of geographic data such as maps, charts, and textual documents as + well as non-geographic data (ISO/FDIS 19115, 2003).</p></div></div><div class="chapter" lang="en"><div class="titlepage"><div><div><h2 class="title"><a name="N1007D"></a>Chapter 3.

Web2 technologies have been adopted, in + particular AJAX techniques, to allow for more interactive and faster + services in the web interface and for the integration of the existing + web map viewer in the home page. Similar functionalities have been + implemented in the administrative part of the system, to provide an + easier access to the configuration pages related to site settings, + catalogue harvesting, scheduling and maintenance.</p><p>The search interface has been completely overhauled to provide + highly interactive searching capabilities. Furthermore, the new version + of GNos embeds GeoServer as map server. Users can now not only overlay + OGC web map services available on the web, but also create their own map + services for other users to browse without having to download additional + plugins. Maps created with web map services can be now saved as PDF and + sent to others.</p><p>The metadata catalogue handles the latest ISO19115:2003 geographic + metadata format based on the ISO191139 schemas, as well as the older + ISO19115 final draft format, FGDC and Dublin Core. The metadata editor + is able to handle the majority of these complex standards, providing + default, advanced and XML editing online tools.</p><p>The new version has a number of different harvesting interfaces + allowing users to connect their own server to many other catalogues + around the world. This is the result of the implementation of the open + source reference for the web catalog services according to OGC + specifications. Harvesting in the new version is now fully compatible + with GeoNetwork 2.0 and 2.1 nodes.</p><p>We have added avanced online and offline administration + funcionalities to configure, backup and migrate the application. We have + also added a convenient import and export format "MEF" or Metadata + Exchange Format, that allows the users to move metadata, previews and + even data in a convenient single file. GNos can be easily expanded with + plugins to export/import metadata to/from other software supporting + MEF.</p><p></p><div class="figure"><a name="N1008E"></a><p class="title"><b>Figure 3.1. <span class="bold">Figure 3.1.
